MIPS: pm-cps: Use MIPS standard lightweight ordering barrier
Since R2 of the MIPS architecture, SYNC(0x10) has been an optional but architecturally defined ordering barrier. If a CPU does not implement it, the arch specifies that it must fall back to SYNC(0). In places where we require that the instruction stream not be reordered, but do not require that loads / stores are gloablly completed, use the defined standard sync stype.
